IPC: B01J23/76
Filed: 1979-11-07
Abstract: PURPOSE: To ortho-methylate a phenol industrially and advantageously in the presence of a multielement catalyst containing an iron oxide obtained by calcining a solid mixture prepared from a dispersion mixture comprising a colloidal iron compound and a solution of a metallic compound, e.g. gallium.  
     CONSTITUTION: A solid mixture prepared from a dispersion mixture containing a colloidal iron compound, e.g. a sol iron hydroxide, and a solution of a metallic compound selected from Ga, Ge, Y, Nb, Hf, Ta and Bi, is calcined to produce a multielement catalyst comprising an iron oxide as a chief component and an oxide of the metal in the above-mentioned solution. The catalyst is effective for methylating a phenol, has a high selectivity for the o-position and is capable of suppressing the decomposition of methanol; therefore, a phenol having a hydrogen at the o- position, is reacted with methanol in the presence of the catalyst under heating to give the titled compound industrially and advantageously.

Title: Cyclone dust collector
Inventor: TACHIBANA KEITAROU
IPC: B04C5/22
Filed: 1978-11-22
Abstract: PURPOSE: To avoid the clogging of dust collector with adhesive dust by hanging down a flexible striker at the inside of outlet pipe of cyclone duct.  
     CONSTITUTION: The inside of the outlet pipe 4 of the unit cyclone duct 1 is provided with the supporter 10, and from the center of the supporter, the flexible wire 11 connected with a striker, e.g., the chain 12, is hanged down. During operation, the chain 12 is swung by gas flow to give a shock to the dust deposit 9 on the lower conical portion 3 in the way as shown by the marks 12a and 12b. The shock vibrates the unit cyclone duct 1 to hasten the falling of dust adhered to the inside wall. The striker has no influence on the gas flow along the inside wall of the unit cyclone duct 1, and thus the separation of dust is not interrupted and also because the striker is hung down at the center, the flow of gas discharged from the outlet pipe 4 is also interrupted.

Title: Headphone
Inventor: TOUNO KOUJI
IPC: H04R1/10
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain the headphone in which a change in sound quality is suppressed even when an output impedance of an audio equipment differs by connecting a resistor in series between an acoustic unit and a headphone plug and connecting a resistor in parallel with the acoustic unit. SOLUTION: A resistor R1L(R) is inserted to a headphone cord 4L(R) interconnecting a left (light) ear acoustic unit 1L(R) and a headphone plug 5 and a resistor R2L(R) is connected in parallel with the acoustic unit 1L(R). With respect to the nominal impedance ZL of the acoustic unit 1L(R), the resistance of the R1L(R) is selected to be nearly equal to 10Ω-|ZL| and the resistance of the R2L(R) is selected as R2L(R) approximately, >=|ZL|and <=2|ZL| so that the drive impedance when viewing from the acoustic unit 1L(R) is not susceptible to the effect of the output impedance of the audio equipment. Thus, even when the output impedance of the audio equipment differs, the open type headphone can suppress a change in the sound quality.
